SZE/ VLSI Technology / M Hill. In the second phase, failure analysis is performed on a fraction of the fabricated wafers to determine the cause of the failure. The transformation of contaminating particles into defects and then electrical faults is a very complex process which depends on the defect location, size, material and the underlying IC topography. This is especially 808 IEEE TRANSACTIONS ON VERY LARGE SCALE INTEGRATION (VLSI) SYSTEMS, VOL. Particulate contamination deposited on silicon wafers is typically the dominant reason for yield loss in VLSI manufacturing. Understanding yield loss is a critical activity in semi-conductor device manufacturing. This paper describes the yield estimation approach to layout scaling of sub-micron VLSI circuits. It also allows to reduce time-consuming extraction of the critical area functions. Yield Loss in ICs Yield loss occurs when there is an unacceptable mismatch between the expected and actual parameters of an IC. Systematic defects are related to process technology due to limitation of lithography process which increased the variation in desired and printed patterns. (b).Parametric yield loss … 226-227, March 1983. SUGGESTED BOOKS: 1. S.A. Campbell / The Science and Engineering of Microelectronic Fabrication / Oxford 2008/2nd edition S.M. Current very-large-scale-integration (VLSI) technology allows the manufacture of large-area integrated circuits with submicrometer feature sizes, enabling designs with several ... the yield loss due to spot defects is typically much higher than the yield loss due to global defects. 16, NO. Yield loss in ICs are classified into two types: (a).Functional yield loss (Yfnc) due to spot defects (shorts & opens). 2009/2nd Edition 2. 6, pp. In designs with a high degree of regularity, such as The most important yield loss models (YLMs) for VLSI ICs can be classified into several categories based on their nature. yield loss. Examples of yield calculations using the proposed method are presented as well. YIELD AND RELIABILITY: Yield loss in VLSI, yield loss modeling, reliability requirements, accelerated testing. loss is due to random defects, and parametric yield loss is due to process variations. The most important Yield Loss Models (YLMs) for VLSI ICs can be classified into several categories based on their nature. S. K. Gandhi/VLSI Fabrication Principles/Wiley/2nd edition 3. 2. Degradation of lithographic pattern fidelity is a major cause of yield loss in VLSl manufacturing. 7, JULY 2008 2% and 4% yield loss, respectively, over the timing yield across The presented method makes it feasible to find scaling factor of the IC design which is optimal from the manufacturing yield point of view. Systematic Defects: Again systematic defects are more prominent contributor in yield loss in deep submicron process technologies. The overall yield is in-uenced by many factors, including the maturity of the fab- ... fect tolerance techniques used in VLSI circuits is provided in [12]. Based on this analysis, ... “Yield Estimation Model for VLSI Artwork Evaluation”, Electron Lett,. Automation of and improvements in a VLSI fabrication process line drastically reduce the particle density that creates random defects over time; consequently, parametric variations due to process fluctuations become the dominant reason for yield loss.
